Letters Patent No. 110,166, dated December 13, 1870.

vIMPROVEMNT IN SELF-ACTING VALVES OR CUT-OFFS FOR LIQUlD CANS;

The Schedule referred to in these Letters Patent and making part of the same.

l and exact description thereof', reference being had to in which- Y 4 Fignrel represents alongitudinal central section of my invention which is attachedto an ordinary oil-can, a portion of said can being removed so as `to show its application thereto, and the position it occupies in relation to its spout or tube when the can is placed in an ipright position or when the contents thereof i are not being poured out or emptied; and

Figure 2 is a similar view of the same, saving the valve, which is represented in a side view and with its upper or tighter end released or thrown out from its the accompanying drawing forming a p'art thereof, and

spout, caused by decanting or tilting the can, as

shown. .t

This invention relates to certain improvements in oil-'cans or other cans or vessels for holding` liquids, and from which the same is obtained through a spout ortube fastened to the top thereof, and passing through the said top with a portion of its surface projecting inwardly in an inclined position, and of sucient length to receive a -cylinder or ferrule or strap, upon which are formed perforated projections or lugs forming a bearing for the fulcrnrn 'of the valve, which consists of a sheet-metal plate, having' formed o n it, at a point near its upper end, right-angular perforated projections or ears, through which `its, axle or fnlcrum passes,

and supplied at its lower end with a weight constructed as hereinafter shown and described.

Similar letters of reference in the several figures i'ndicate corresponding parts. In the accompanying drawing- A is an ordinary oil-can supplied with the top B, which is screwed thereon., y

O is a tube inserted through an orilee or aperture in the top B in 'an inclined position, and acting in the capacityof a spout, through which the contents of the can A may be poured out.

V To the inner projecting end of the spout C is fastened a metallic `strap,'c, the pendent ends of which are supplied with apertures, through which passes a key or rod, c, after having tirst passed through the perforated right-angular projections or ears d formed on the plate l1 of valve D, thereby Vconnecting and pivoting the valve to the spout C.

D is the valve, which consists of the flat-metal plate lll formed at a point nearits upper end with the rightangular perforated projections or 'ears d, at which points the said valve is pivoted, and of the weight di, which is screwed to the said plate d.

The plate d* of the valve D is slightly curved ator near its center, in the manner shown in the drawing, for the purpose o f allowing its loaded or weight portion to be readily'relieved from the spout.

cz is a vent-tube.

It will be seen lfrom the foregoing that, when the can is resting or standiugin an upright position, the valve willclose its spout by its own action, and that, when the can is tilted or decanted i'or the purpose ot' emptying-its contents, or -a portion thereof, as the case may he, the valve will, Abymeans of its weighted portion and the` inclination given to the can, be withdrawn from the inner end of the spout C, thereby allowing the contents ofthe can to enter saidfspont and be relieved therefrom or emptied.

Having thus described myinvention,

What I claim, and desire to secure by Letters Patent, is-

A self-actingv valve or cut-olf, consstin g of the valve D, composed of ears ll, plate all, and weight d2, arranged to operate substantially as set forth.

In testimony that I claim the foregoing as my invention, I have hereunto set' my hand this 14th day of November, 1870, in the presence of two subscribing witnesses.

Witnesses: HEMAN S; SNOW.
